28、ope This part of IEC 34 specifies the IM code, a classification of types of construction and mounting arrangements of rotating electrical machines. Two systems of classification are provided as follows: The type of machine not covered by Code II should be fully described in words. The relationship b
29、etween Code I and Code II is given in Annex A. 1.2 Definitions For the purposes of this part of IEC 34, the following definitions apply: 1.2.1 type of construction the arrangement of machine components with regard to fixings, bearing arrangement and shaft extension (IEV 411-13-34) 1) 1.2.2 mounting
30、arrangement the orientation on site of the machine as the whole with regard to shaft alignment and position of fixings (IEV 411-13-35) 1.2.3 shaft extension a portion of a shaft extending beyond an extreme bearing (IEV 411-13-07) NOTE The bearing may be on the machine itself or be part of an assembl
31、y comprising a machine and (an) additional bearing(s). 1.2.4 drive-end of a machine (D-end) that end of the machine which accommodates the shaft end (IEV 411-13-36) NOTE This is normally the driving end of a motor or the driven end of a generator. Where for some machines the above definition is inad
32、equate, the D-end is defined as follows: a) machine with two shaft extensions of different diameter: the end with the larger shaft diameter; b) machine with a cylindrical shaft extension and a conical shaft extension of the same diameter: the end with cylindrical shaft extension; c) machine with oth
33、er arrangements: according to IEC 34-8 if applicable; otherwise by agreement. NOTE The outer diameter of a forged-on flange is taken to be the diameter of the shaft extension. 1.2.5 non-drive end of the machine (N-end) that end of the machine opposite to the drive end (IEV 411-13-37) Code I (see sec
34、tion 2): An alpha-numeric designation applicable to machines with endshield bearing(s) and only one shaft extension.
